Charges Q_1 and Q_2 are at points A and B of a right angle triangle OAB (see figures) . The resultant electric field at point O is perpendicular to the phypotenuse, then Q_1//Q_2 is proportional to :

If the tangent to the ellipse x^(2)+2y^(2)=1 at point P((1)/(sqrt(2)),(1)/(2)) meets the auxiliary circle at point R and Q, then find the points of intersection of tangents to the circle at Q and R.

If PQ is the focal chord of the parabola y^(2)=-x and P is (-4, 2) , then the ordinate of the point of intersection of the tangents at P and Q is

An equation chord joining the points (1,2) and (2,-1) subtends an angle of pi//4 at any point on the circumference is
